T 0 all w hom t may concern Be it known that. I, JOHN FRrrsoHn, a citizen of the United States, residing in the city and county of Philadelphia, State of. Pennsylvania, have invented a new andl useful Apparatus for Dispensing Liquids,

of which the following is a specification.

In my prior Patent, No.'l,l99,065, dated September 26th, 1916, of which the present application is a divisioml have described and broadly claimed, a novel construction' for vending a plurality of liquids, and my present invention relates moreparticularly to a novel construction of a measuring device, whereby a predetermined amount -of liquid is dispensed at each cycle of the operation.

It further .consists ofv a novel construction and arrangement of a--ineasuring cup or receptacle and novel means for control# ling the admission of liquidk from themain receptacle to said measuring Vcup and its discharge therefrom.

It further consists of a novel construction and arrangement of a Vdouble wall'container, whereby the liquid .to be vended may be maintained at a'desired temperature, and novel means-for controlling thel discharge of liquid from the apparatus.

Other novel features of construction and arrangements will hereinafter more clearly appear in the detailed .description of 'my invention.

For the purpose of illustrating one manner of carrying out my invention in prac' tice, I have shown inAv the .accompanying this embodiment is ktypical only and that the various instrumentalities..'oflwhich my invention consists can be variously arranged and organized and that Vit is notlimited to the precisefarrangement and organization of these instrumentalities as herein set vFigure l represents a rear elevation of an apparatus for dispensing liquids embodying my invention.

Referring to the 'drawings:-. l designates the rframe-work'of the appabe varied widely sin'` practice.` ToA this frame-work is secured in any desired man-v ner, a front wall 2, (see F ig. 8), to which the coin 'or check-controlled mechanism is connected.

The coin-controlled mechanism.

Any desired or conventional' type/.of coin-controlling mechanism may be einl ployed, vbut for convenience ofiillustration, l have shown the saine ymechanism Vas that disclosed in my co-pending application .to reference has hereinbefore been which made. rl`he front wall Q'l'ofVV the` 'housing ofthe apparatus is provided with 'an `opening '3 into which the coin or check is inserted, andv such inlet registerswith-a vcoin chute 4,'through which' the `coin will kpass if it is of the prop'er dimensions, and fall into the inclined slot'5` of a coin wheel 6,

ratus, the form and contour o'f whichv may i which is fixed toa shaft 7, which latter is llliournaled in the frame-worlrof the in any desired manner.

8 designates ka disk the hub of the .coin wheel 6,2see y,127,

machine 'loosely Vmounted on' Vandfthis disk 8 is .providedlwithfavvlugrf) chine.

which travels in a recessed portion 10 of the vcoin wheel 6 so as to engage a coinV which has been retained in the slot 5 of" the coin wheel. The disk 8 is provided with a segmental rack 11, which is in mesh with a pinion 12 carried by a rotatable shaft 13 which extends through the lfront plate 2 of the machine housing and is provided ywith a-grasping portion 14. The shaft or 10,

such as for example, the coin return'chutel 17 which delivers the rejected coin to a receptacle 18 located exterior of .the ma- 19 designates a spring, one end of which is fixed to the rod 13 and the other end of which is connected to a stationary portion of the machine so that the rod 13 norf mally remains inthe position seen in Fig. 8.

nThe coin which has served to interlock the coin-wheel 6 and the disk 8 passes into the conduit 20 on the; rotation ofthe coin wheel and disk and is received in a coin receptacle 21 of any desired type and preferably one which is removable and which can be locked in position. Y

VVReferring now more particularly to Figs. 9, 10 and 11, it willbe seen that the shaft 7 has keyed or otherwise fixed thereon a cam.

member 22 which is provided with a boss or bearingmember 23 having a slot 24 in its periphery, which is illustrated as having a V-'shape contour and which is adapted to interlock with al plunger 25. This plunger 25 has Va longitudinal slot 26 in its periphery, into which extends a set screw 27 to prevent rotation of the plunger 25. The plunger 25 is also providedy with a stem 28 and a' spring 29y is interposed between the'plunger and a nut 3() which closes the lower end of the sleevef31, in which latter, the plunger is slidably mounted. Y f

32 designates nuts on the plunger stem 28, one of which serves as a lock nut. The cam member 22 is provided on one of its sides with a cam-shaped recess 33 which normally receives an anti-friction roller 34 carried by a pin 35y whichis secured by means. of a nut -36 to a lever .37, which is fulcrumed at 38 to `:the frame of the machine.

of the lever 37.is bifurcated and provided` The lower end with oppositely disposed anti-friction rollers 39 secured` thereto in a similar manner to that already described with reference to the ber 41 carries a-sprocket wheel 43around which passes a sprocket Vchain 44. Said sprocket chain also passes around the vsprocket wheel45 fixed on the shaft 7 46 designates a clutch member loosely 4liquid container 70 is seated.

:mounted on the shaft 42 Yand whose movement toward the clutch member 41 which is vkeyed to the shaft is limited, as will be un-v derstood by reference to'my priory patent, toy which have heretofore referred. The clutch member L46 is provided with a disk 47 having reversely inclined Vfaces at its periphery, with which spring clips 48v are adapted to engage.. y i

V49 designates a spring which tends to move the clutch member 46 toward its abutment on the shaft 42. 50 designates a sprocket wheel carried by the coupling member 46, and coperating with this sprocket wheel 50 is a sprocket chain 51 which .passes around the sprocket wheel 52 mounted on a shaft 53 journaled in the frame-work of the machine. 54 designates a` gear on the shaftv 53, which meshes with a pinion 55 on the drive shaft of an electric or other motor 56. f

Referring now more particularly to Fig.

2, the shaft 7 has secured thereto in any desired manner, a cam or eccentric 57 ,which is located in the recess 58 of a lever59, which is pivoted at 60 to a fixed portion of the framework. Theopposite end of Vthe lever 59 is connected with a link 61, which `in turn l a flange 68 and a gasket69, which rests' on the bottom of a liquid containerA 70. The bottom of the liquid container 70 rests upon a gasket 71 which is supported upon a tubular casing 72, which is inwardly deflected at its lower end to support the measuring cup 67 and the bottom of said casing 7 2,rests on a gasket 73 which is seated on the bottom of an outer liquid container7 4.

V75 designates a nut in threaded engagement with the sleeve 66 and adapted to bear against the `bottom of the outer liquid container 74 in order to maintain the measuring v cup in sealed condition with rrespect to the inner and outer liquid containers. The outer liquid container 74 is provided with an inwardly extending ange 76 upon which the downwardly deflected portion77 of the inner such as for example, water, in the louter container 74, ismaintained at a desired temperature by passing hot water, steam, or other temperature changing medium through the conduit 78 which passes through the chamber of the outer container 74.

79 designates a liquid gage (see Fig. 1') for the inner container 70,-and 80 designates a similar gage for the outer liquid container The liquid, f

74, and leach of these gagesl arey provided with a drain cock, as will beunderstood by reference to Figgl. Y y 81y designates a spout through which the outer container may be filled without removing the cover 82. The inner wall of the measuring cup 67 at its upper end forms a I valve seat 83 for a valve 84, which .is illustrated as consisting of a cup-shaped valve having a closed top 85, which is provided .Y with a flange 86 which rests on the top of they measuring cup 67. l87 designates a port `in4 its upper portion has a Vconical wall90, saidv walls coperating with seats of Vcorresponding contour. in the measuring cup. rllhe valve-stem has a reduced end'which 1s keyed to the top of the valve 84 and such valve stem is fixed in position by means of a nut 91 bearing against the top of the valve and in threaded engagement with the [valvestem. rlhe valve-stem isflongitudinally grooved, as at 92, see Figs. 4 and 7 so that upon a partial rotationofv the valve stem, a'discharge port 9-3 will berplaced in com! munication with-.the chamber ofthe measurin'g cup and the liquid to loe vended will flow by gravity through thel 'discharge conduit 94, which conducts the liquid to apoint accessible to the purchaser.- lVith some liquids, such as for example, chocolate or milk, it is desirable to frequently agitate the liquid, and I therefore eccentrically connect with the valve, a rod 95 having a .desired numberv of agitator barsv 96 of any desired contour, which are adjustably mounted on said rod. The lower end ofthe sleeve 66 is provided with a stuffing-box 97 of any desired type'. Y

The operation of my invention will now be apparent to those skilled inthis art and is as follows: f l

The intending purchaser insertsa coin of the proper denomination inthe coin slot'3 and lthe coin passes through the chuteA 4 into the coin slot 5 in the coin wheel 6. The' intending purchaser then turns the handle 14 in the proper direction and the pinion 12 meshing with the rack 11 will cause the disk 8 to rotate, and the lug 9 pressing against vtheslot y5 in the coin wheel will cause the disk 8 and the coin wheel 6 to loe interlocked and effect a partial. rotation of the shaft 7 rllhis causes the spring-pressed plunger 25 j with the continuouslyrotating clutch' memi ber i 46. Owing to the provision of the sprocket wheels'50 and 52, andthe sprocket chain 51 and the shaft 53 operatively connected withthe motor, the shaft 7 will be rotated` one revolution, lwhereupon vthe roller 34 willagain enter thecam recess 53,'there-V by rocking the lever 37 and disengaging the clutch members The Vspring-pressed plunger 25 will. interlock withthe recess 24,-and the shaft 7 will be retained in its ynormal position. If for any reason the parts shouldv jam, the machine is rendered fool proof and` any damage tothe machine prevented, owing to the resilient mounting of the' clutch member 46.

'The ClutCh member 46 will ybe moved outg' I Y n wardly and the spring-actuated clips 48 will 1 engage the inner of the vinclined iwalls vof 80' i* the disk 47 and hold'the clutchmember 46 i out' of its clutch engaging position. The ro tation of the `shaft 7, as above described, rotates the cam 57, thereby reciprocating the rack 62, and as this rack meshe'slwith the pinion 64, the valve-'stem 65 and the valve 84.will be partially rotated.y This causes 'the inlet port 87 .of thetvalve to move out of register withthe port 88, and the-groovel 92 will be brought into register with the discharge port 93 so that'the liquid will passI Vby gravity through the deliveryv conduit94'. The valve is returnedto .its initial position,

` and the ports 87 and 88 are again brought into register, and the measuring cup is again filled with liquid Aduring the next deliveryf operation. n .n

It will be apparent that the amount of liquid which is discharged from thefinner' container 70'may be varied by either changv v100 ing the measuring cup .andsubstitutingffory Vit a measuring cup of largerdimensionsor by varying the dimensions of the valve to vary the amount of liquid which the measur,y

ing cup will contain The valve of the ,1053

measuring device for the inner liquid con-' tamer is preferably timed 1n such av ina-nner that the measuring cup is empty at the beginning of the operation and is Vlled after a. predeterminedirotation of the'valve stem -110 which causes the ports 87 and 88; to be'A brought into register. If desired, a burner 98 may be employed -to heat the liquid in the outer container 74.

It will be understood that in vpractice preferably employ a continuously rotating shaft 53, and while I have illustrated but a i ,singlel unit, a number vof these units are employed which are driven by this continu-f ously rotating shaft, and independently actuated bythe insertion of a coinpor check into-the machine of proper denomination. I have shown in Fig. l the shaft` 42 asadapt'-` edto control a second liquid container 99,

Ybutas this second liquid container forms per se no part of my present invention, yI

have deemedl it unnecessary to illustrate and y describe'th'e same in detail.,` Y A t It will now be apparent thatjl` have'jde` I vised a novel and usefulapparatus forwdis-4 v.V130 i pensing liquids, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While I have,`in the present instance, shown and described a typical embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible f of modification in various particulars withthe invention or sacrificing any of its adout departing from the spirit or scope of vantages.
